It would be nice if you'd be able to share information through a direct (or 'outside the game' server) line to another player without going through the game. Like I would like to create a script so me and another can see each others health/mana/defenses/afflictions etc, now it can be done through the game but that would create a lot of spam and sometimes players aren't able to talk with each other. So having a direct line from client to client would eliminate this need. It could also function as a personal chat that game admins wouldn't be able to listen in on
